<DIV>Hi,</DIV>
<DIV> </DIV>
<DIV>Im developing an online traffic information system using Pgdijkstra
Routing Module. Everything works, fine. But need a small help. In Pgdijkstra
Routing Module, when the shortest path is selected it assumes that it can
travel any direction at any junction. (say it is reaching the junction
then it can travel to all other directions). But we know that in real
life, sometimes it is controlled and it can't travel to all the directions.
(some directions are not possiple). I think u got my point. (this is not
making a road segment oneway or closed. It's possible to be done). So I
don't know how to implement that. (controlling the directions which it can
travel). If you can please help me.</DIV>
<DIV> </DIV>
<DIV>Thank you in advance.</DIV>
